If youre planning on using a 944 as a D, my bet would be the roads would kill your car and you back. Roads are bad enough in several first world countries as it is...

Generally, third world nations (like Nigeria) will have a decent contingent of exotic vehicles. In such nations, a small minority control the bulk of the wealth and will often flaunt their wealth. The ability to flaunt wealth in such nations is also linked to your "alternative" means of income. In poor nations if you flaunt weath, you need the backing of and association with organized crime since everyone wants what you have. I'm not sure of your employment but a majority of foreigners who work in Nigeria are associated with the petroleum industry. Many live in Company run enclaves that are segregated from the local population for safety reasons.
I would not necessarily link wealth to "alternative" means of income. There are plenty of legitimate business people in Nigeria with high incomes that enjoy their high end cars. Of course, there are also huge numbers of super poor people and many rich criminals living alongside the upper class. I have lived and worked in many countries and Nigeria was probably the most interesting.

A 944 is not a very expensive car. If the roads eat it up, I will sell it locally. I have never had an issue selling my cars overseas.

At 8600 feet, the air has about 75% the amount of oxygen as compared to sea level --10.9 psi compared to 14.7. That creates proportionally lower cylinder pressures and reduces the propensity for the motor to knock. My guess is they know exactly what they're doing there in Bogota. 85 octane at that altitude probably does just fine for most cars (as long as they stay up there in the thin air). You can reset the FQS as folks suggested, and check to make sure your altitude sensor is connected and working. It is tucked up behind and to the right behind the glove box, and is the yellow zinc canister about the size of a baseball. You might also install a manual boost controller and knock counter ($100 all in) before you head down there, so you can see if it is knocking when you get there and, if so, just turn down the boost a tad. I'd suspect you'll do just fine with some boost, as long as everything else is working correctly. Seems unnecessary to completely eliminate all boost, but with a controller you can turn it down as needed. If you wanted to stay on the performance train down there, consider a water/meth injection system (e.g., aquamist). Water is available everywhere, and should allow 85 octane easily outperform the typical 91 unleaded available on the west coast. (Might want to change your fuel filter before you go too...) Buena Suerte!

Don't get me wrong, I'd get the highest octane available in Denver or anywhere else. I was just saying that 85 octane at 8600 feet may not be as bad as it sounds -- he may not need to eliminate all boost -- and might be manageable with a knock counter, boost controller and FQS settings. I was reacting to the idea of pre-emptively eliminating all boost.

An S2 requires premium fuel. How would a 1987 Porsche 924S be in Bogota? The 1987 924S has lower compression than a 944 for the same year and runs on regular. Porsche purposely dropped 10 hp so that the 924S would not be faster (less weight and drag).
There is a super clean 924S for sale in PA with 35k original miles for sale for $6k. I am considering make a trip to PA to check it out. Any thoughts about original timing belts, head gaskets and oil cooler seals on a 25 year old car? I am guessing that I would want to replace them immediately even though the car is low miles.

I thought it was just discussed that with lower cylinder pressure at altitude, 85 octane would be ok... it mustve been a dream ![Stick Out Tongue](https://rennlist.com/forums/images/smilies/tongue.gif)
I believe brazil has e-100, and probably many other blends of ethanol, but im not sure about columbia. FWIW, I was in central america last year, and didnt notice e-85 anywhere.

In-fact, an 11:1 car at that altitude probably has similar cylinder pressures to an 8:1 car at sea-level.
